Comparing the performance between an R MapReduce program and a standard R program
Those not familiar with how Hadoop works may often see Hadoop as a remedy for big data processing. Some might believe that Hadoop can return the processed results for any size of data within a few milliseconds. In this recipe, we will compare the performance between an R MapReduce program and a standard R program to demonstrate that Hadoop does not perform as quickly as some may believe.
Getting ready
In this recipe, you should have completed the previous recipe by installing rmr2 into the R environment.
How to do it...
Perform the following steps to compare the performance of a standard R program and an R MapReduce program:
- First, you can implement a standard R program ...
